Hi, all

May I know the numpy status for PyPy? Can it be run with PyPy?

I git clone the source code from https://bitbucket.org/pypy/numpy.git https://bitbucket.org/pypy/numpy.git, but seems it’s not been maintained for several years.

And what’s the difference from the numpy for CPython(https://github.com/numpy/numpy)?  Any specific modifications?

Thanks.

Don't use that. Use

pypy3 -mensurepip

pypy3 -pip install numpy

If you are on linux64, this will install a binary wheel just as on CPython. If you are on win32, you will need to wait a bit for the binary wheel; it should appear soon.

For more information, see https://doc.pypy.org/en/latest/faq.html#what-about-numpy-numpypy- micronumpy

https://bitbucket.org/pypy/numpy.git It's numpypy, which is not maintained yet. "pypy3 -mpip install numpy", Does this cmd install the numpy (https://github.com/numpy/numpy) ? Does the same numpy support both Cpython and pypy ?

Did you read the link I pointed to?

If something is not clear with the information there or you have an idea how to make it more prominent then it should be fixed there via filing an issue at

https://foss.heptapod.net/pypy/pypy/-/issues

Yes, I did. Thank you. But after I install numpy for pypy, there are some errors. Not sure anybody met before: Python 3.6.9 (2ad108f17bdb, Apr 07 2020, 02:59:05) [PyPy 7.3.1 with GCC 7.3.1 20180303 (Red Hat 7.3.1-5)] on linux Type "help", "copyright", "credits" or "license" for more information.
